COIN-OPERATED VENDING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 470,508, dated March 81892.

Application filed October 8, 1891.

To allan/hom it may concern,.-

Be it known that I, JOHN SCHADE, a citizen of the United States, `and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Coin-Operated Vending Apparatus; and I do declare the following to be a full, clear, and exact description .of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings isa representation of the lnvention in plan'view, showing the .parts in normal position. Fig. 2 is a similar view showingthe partsin dischargingposition. Fig. 3 is a vertical transverse section on the line o; x, Fig. l. Fig. 4 is a bottom planview 0f the faceplate. Fig. 5 is a detail perspective View. Fig. 6 isa vertical section of a portion of the plug. Fig. 7 is a horizontal section through a portion of the rotary plug and its bearing. Fig. 8 is a detailview of the cutter. Fig. 9 is a sectional view showing the operating mechanism as applied toa conveni` tional form of goods-holder.

This invention has relation to coin-operated vending-machines in which the article purchased cannot be delivered until prepaid by a coin of the size and value denoted by the rprice of the article; and it consists in the novel construction and combination 'of parts, as hereinafter specified.

The primary object of the invention is to greatly simplify the construction of the machine and at the same time provide more efficient means for preventing it from being fraudulently operated either by the insertion of a coin of a different denomination than that calledb for, by the insertion of a coin sufficiently to permit the machine to be operated and subsequently withdrawing it by means of a string or other medium attached to .the

coin, or by the insertion of any article other than a coin, or in any other improper manner. Other objects of the invention will hereinafter appear.

In the accom pan yin g drawings I have shown land will hereinafter describe a machine of this character which is adapted to be operseria No. 408,159.' oa man.)

atedby the insertion of a one-cent piece; but it willA be understood that I may adapt the machine for operation by a coin of any other denomination, according to the particular use to which the machine is to be put. t

` y In the drawings I have shown the operating mechanism only, which is designed to be inclosed in any suitable casing or closure providedwitha chamber or chute B, (shown in the plan View, Fig. 1, in dotted lines,) in which cured tol this faceplate is a hub or sleeve E,

having a circular chamber extending therethrough, in which bears a plug or cylinder F.

Theupper portion of the sleeve E hasaninward iiange e, against which fits a shoulderf,

formed by thevreduced diameter ofthe upper portion of the plug, said ange and shoulder forming an additional bearing. Th rough this plug F "is a vertical transverse slot G, the end walls of which terminate short ofthe circumferential edge thereof. On the upper end of said plug is a lug or ear g, to which is connected one end of a link G', the opposite end being connected to an operatingknolo or but-v ton II. To the upper end of said plug is also lconnected an arm I-I, provided at its free end with a short arm h, the forward end of which normally lies just at the rear of the lower portion of the chute B, and which is adapted under the lmovement of the plug to project into said chute and to engage and throw out at the delivery an article or package therein.

H is a spring connected to the plug and designed to return it to its normal position after operation. The Vrotary movement of said plug in the sleeve is limited by the stud or pin projection h', carried bythe shoulder f and engaging atV opposite limits of movement the end Walls of a slot I, formed by a cut-away portion of the iange e of the sleeve E.

The lock for the purpose of preventing the plug from turning to actuate the push-arm Il to cause the delivery of an article orpackage from the chute except by the insertion of a' coin of the proper size and denomination in the slot G will now be described.

ConnectedtothesleeveEarethearmsorlugs J and J', having therein each a horizontal longitudinal apertureorborej,extendingthrough the inner periphery of the sleeve, and in these lugs are respectively seated pins or tumblers Za Zr', which under the action "of springs 7c are designed to be thrown into engagement, respectively, with apertures Z Z in the plug F and prevent said plug from turning in its sleeve or bearing. The aperture Z extends throughthe plug to the slot G and ycommunicates therewith centrally4 of its len-gth, while the aperture Z communicates with said slot at one end thereof.

and m', respectively, and when the position of the plug is such that said apertures are in alignment with the pins or tumblers 7n and Zt y said tuinblers will act against the pins fm, m

to `project them slightly into the slot G. Said aperturesZ Z where they enter the circumferential edge of the plug are provided each at one side with a bevel or run-out n. Vhen the plug is in its normal position,- the tumblers or pinsZc and 7c are in engagement with these run-outs and do not Acontact with the pins m and m to project them into the slot G,

y said slot and falls therein by its own weight.

The operating knob or handle is pulled out-v wardly, causingthe plug to turn in its sleeve, and as it turns the apertures Z and Z are brought into alignment with the pins or tum.- blers 7c and Z0', which consequently are forced by their respective `springsinto contact with the pins m and m. The position of the coin, however, prevents said pins from project-ing into theslot G, and they are therefore caused by ,said coin to react against the tumblers sufiiciently to force them back out of .en gagement with the plug, which is then free to turn sufiiv ciently to operate the delivery-arm H. As the v tumblers 7c Za d o not normally contact with being therefore necessary) the edge of the aperture d of the face-plate D is provided with the cams or inward offsets o, which are located at diametrically-opposite points andv project over the end portions of the slot G sufficiently Vorkin g loosely in these apertures Z and Z are pins m to prevent the complete passage of the coin therethrough until the plug has been turned the correct distance, when said slot will have been carried away from said projections and the coin allowed to fall through. Said projections also serve to prevent the coin from being again drawn up into and through the slot by a string or other medium after it has once been used. When the article or package has been delivered, the spring retracts the plug and push-arm to their normal positions. To prevent the operating-knob being successively operated after the plug has once been unlocked by the coin and the consequent delivery of a successive numberof articles,which might be done'by preventing the plug from coming back quite far enough to be locked by the tumblers, the chute B is set back suiiiciently far so that after an article has been delivered by the action of the arm'H the subsequent article, instead of falling in front-vof said arm, will fall thereon and wil-l be retained there until the arm has been retracted to the point where the tumblers will act to effect the lock. Then as the tumblers come into engagement with the run-outs the arm is still further retracted, and the package falls in front of it in position'to be delivered by the subsequent complete operation.

The slot G is made of exactly the proper diameter and width to receive a one-cent piece, and to prevent the use of a disk of softer material of exactlythe same thickness and diameter the wall of said slot opposite the pin m is provided with the oifset P. Suppose a diskof soft material is inserted in the slot and the knob pulled. The tnmblers will throw the pin m against said disk, forcing it into said offset, and said disk, owing to i-ts soft character, will not react against the pin sufficiently to throw the tumblers back `out of engagement with the plug and the machine a washer, the pin m will be projected through the central cut-awayp'ortion thereof and the machine will still remain locked. A coin ofl a thickness or diameter a little less than a cent-piece willfall directly through the plug and will not remain in position to operate7 and a larger coin will not enter the slot at all. Suppose, however, that a coin or disk is used which is of the same diameter as acent-piece, but which fails to have quite the same thickness. In this case a reaction would be given the pin m and the tumbler Zt would be thrown back out of engagement with the plug, but the pin m would vnot operate and the machine remains locked. If the reverse is the case and the thickness the same, but the diameter not equal, the pin on would not be operated. It is of course obvious that a r-igid disk corresponding exactly -in thickness and diameter to a cent-piece will operate the -inachine,.and in s/ome instances this may bedesirable. To prevent the pin m from being proj ected by the tumblers or drivers far enough IIO into the slot'G to. prevent the coin from passing through, the bore or aperturel is offset inward or reduced in diameter near Where it communicates with said slot, the pin being correspondingly shouldered for engagement therewith.

lf the cam-edge of the face-plate aperture is not-a sufficient guard against a coin being used with a string secured thereto, a knife or cutter R may be provided,rwhich as the, plug is turned will be in position to sever the spring. This cutter, as shown, may consist of an .approximatelyy semicircular plate secured to the rotary plug. Said plate is cut awayso that its edge r extends along one edge 'the spring S. V

By'placing the run-outs on the opposite side of the apertures l Z the device may be operated by a push instead of a pull movement. i i i l The coin falls intooperating position entirely by gravity and does not require to be Y pushed into the slot.

It will be understood that l donot wish to limit myself to any particular form or style of `the case or closure nor to the exact arrangement of minor parts, as described.
